AUGUSTUS B. DAVIS, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN RAILWAY RAlL-SPLICES.

Specification forming part of Letters Patent No. 126,035, dated April23, 1872.

Specification describing an Improved Rail- Splice, invented by AUGUSTUSB. DAVIS, of the city and county of Philadelphia, State of Pennsylvania.

Improved Rail-Splice.

My invention consists of two bars, one or both of which is elastic, thesaid bars being adapted and bolted to adjoining rails, substantially inthe manner described hereafter, and the whole forming a simple andeconomical device for serving the twofold purpose of splicing twoadjoining rails and retaining the nuts of the bolts.

In the drawing, Figure 1 is a transverse section of a rail with myimproved elastic splice; Fig. 2, a sectional plan on the line 1 2, Fig.1, and Fig. 3, a modification of my invention.

On reference to Figs. 1 and 2, A and A are two substantial but slightlyelastic splicingbars, which I prefer to make of steel, but which may bemade of wrought-iron, rendered slightly elastic byv cold rolling orotherwise. Whether these bars be of steel or iron, I consider it best tobend them while cold to the desired segmental form represented. The barsare made to fit the adjoining rails, as shown in Fig. 1, and aresecured, with their convex sides against the rails, by simple bolts B B,on tightening the nuts a. a. of which the bars will become fiat, ornearly so, and yet possess such inherent elasticity that their tendencyto recoil and assume their original segmental form will prevent the nutsfrom turning.

On tightening the nuts the bars will have a slight tendency-to springoutward in the middle, and this may be counteracted by the introductionof a bolt near the ends of the rails; but this bolt is not essential incarrying out my invention, although it is to be preferred for theheavier class of rails demanding long pressure against the bolt-head,nut, or washer,

substantially as described.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.
